What action should the official take when the warning horn sounds with 15 seconds remaining during an interval for player replacement?

When the warning horn sounds with 15 seconds remaining during an interval for player replacement, it is important for the official to ensure that all players are ready before the game continues. This action reflects proper game management and ensures that both teams are prepared to resume play without any confusion or delays.

Taking this approach allows the official to confirm that substitutions have been completed properly and that both teams are set to engage in play with the appropriate personnel on the court. It is essential for maintaining the flow of the game and upholding the standards of officiating.

Additionally, ignoring the warning sound or assuming that play can proceed without checking that teams are prepared can lead to issues on the court, such as mismatched player lineups or confusion regarding the game's status. Therefore, confirming readiness is critical to ensuring a smooth transition back into gameplay.
